Hdi Clutch On 2,0t

[boeseturbo 1]

Dear friends,

 

I looked at the HDI flywheel and TCT flywheel.

 

Some facts:

 

- HDI Flywheel is much heavier

- HDI clutch-disc / case don't fit to TCT flywheel

- HDI Flywheel don't fit on petrol engines (trigger-teeth are different).

 

Now my idea is to build a cnc-made flywheel, with TCT trigger for HDI clutch, which will weight not more than TCT flywheel.

 

Will anybody interested in this? I will make a small serie with this flywheels. I think nobody will have a problem with torque

when he use Sinterdisc and Helix clutch-case, I think it will hold easily 450 NM.

 

Only thing is, I believe this clutch will only fit into BE3R gearbox not in BE3...

 

I think it will be possible to develope this flywheel for a price about 300 EUR each.

 

Cheers

Hi Jan, is it not better to use the XU10 flywheel and an appropriate heavy duty clutch if you are staying with a BE transmission?

 

I say that as there are lightened flywheels available off the shelf, as are uprated clutches for the XU10+BE combination, hence giving a large saving in cash outlay, TTV do a Lightened XU10 flywheel that is sold through Lynx power engineering that is used on their 400 bhp + Rotrex GTI6 conversions, unsure which clutch they use on them but they are mostly on the BE3 / 4- 6 transmission.

 

What is it about the HDi clutch that makes you want to use it? they aren't particularly strong it seems from the many reports of standard units slipping on remapped 306 HDi's, they run upwards of 220 LBFT and 150 bhp.

 

 

All pure observations however, no real experience of them on anything but standard engines!

Dear Welsh,

 

idea is, the hdi clutch has 230mm diameter not only 215mm ) I will post tomorow a bit longer.

Did a bit of research on this a while back -

 

I bought my new clutch today I didnt go for the HDI one in the end as I phoned valeo technical and found out the torque limit of it:-

 

306 2.0 HDI - 253 NM - Part number valeo 826201

405 1.9 MI16 - 275 NM - part number valeo 801042

 

So it appears that the mi one is better even though its a smaller diameter (mi is 215 mm whereas the hdi one is 230mm) and its quite a bit cheaper too Happy days!

Yes, the HDI runs a different diagphram spring, so even though the clutch is bigger, the torque load it can take is lower, due to less clamping pressure.

I see yes, with the benefit of still fitting in a BE3R casing which the TCT flywheel does not I believe.

 

BE3R was introduced on September 7, 1998 from the data shown on servicebox, seems to be for every engine as well not just the DW10.

 

Would be interesting to see the difference in the BE3 to BE3R casings

 

I see you say the HDI clutch is 230mm, is that the 306-Xsara or Partner/Berlingo one? as the 406 one is 235mm, DW10 only used ML5T in the 406

 

(Servicebox does not list the diameter for the BE3R DW10 clutch plate!)

 

 

edit: missed the two replies there, took me some time to type my reply

 

seems the HDI is only usable if a better Spring Diaphragm is used.
